In this study, we investigated whether changes in mitochondrial abundance, ultrastructure and activity are involved in the respiratory cold acclimation response in leaves of the cold-hardy plant… (More)

Reverse-genetics was used to evaluate the role of an Arabidopsis homologue of the human and yeast FIS1 genes, which are both involved in mitochondrial fission. Two independent T-DNA insertion mutants… (More)

Little is known about the genetic control of mitochondrial morphology and dynamics in higher plants. We used a genetic screen involving fluorescence microscopic analysis of ethyl methane sulphonate… (More)

A mitochondrial-GFP construct was used to tag mitochondria fluorescently in a T-DNA knockout line for the Arabidopsis dynamin ADL2a. Visualization of mitochondria in vivo demonstrated that disruption… (More)

Ammonia assimilation in chloroplasts occurs via the glutamine synthetase/glutamate synthase (GS/GOGAT) cycle. To determine the extent to which these enzymes contribute to the control of ammonia… (More)

An important component of metabolic regulation is compartmentation and specialization. Subcellular compartmentation and the role of individual organelles is well studied, though less consideration… (More)

The distribution of glycine decarboxylase (GDC) in leaves of pea (Pisum sativum L.) and wheat (Triticum aestivum L.) has been investigated using immunogold labeling of the P-protein subunit of the… (More)
